458414 divided by 18 
We're looking to find how many times 18 goes into 458414.

On to step 1:
4 divided by 18 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 18

Moving on to step 2:
If we divide 45 by 18, we get 2 and a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 36 from 45, we get 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 18

Advancing to step 3:
18 goes into 98 5 times with a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
The remainder is 8 after subtracting 90 from 98.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 18

On to step 4:
18 goes into 84 4 times with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 254.0
Subtracting 72 from 84 leaves us with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 18

Going ahead to step 5:
18 goes into 121 6 times with a remainder of 13.
Use 6 as the next digit of our solution. 
Result so far: 2546.0
Subtracting 108 from 121 leaves us with 13.
Fetch the next digit (4) from the dividend, attach it to 13 and continue: 134 / 18

Moving on to step 6:
If we divide 134 by 18, we get 7 and a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 25467.0
If we take 126 away from 134, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
18 can be fit into 80 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 25467.4
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
The number 18 fits into 80 4 times, leaving a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 25467.44
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 25467.44, and the remainder is 0.008.
